Abstract Fluorescent molecular probes have gained significant attention due to their exceptional attributes, such as enhanced specificity, sensitivity, and reversibility. This review explores how organic probe molecules' fluorescence properties change when metal ions like Hg 2+ bind the receptors. The alteration in results from distinct photophysical mechanisms photoinduced electron transfer, proton energy charge excimer formation, aggregation‐induced emission, C═N isomerization etc. Besides, induce chemical reactions resulting changes structural conformation properties. As a result, this effect specifically affects signal of molecules, which is beneficial for advancing sensor technology developed detect contamination. Focusing on environmental pollution biological sample analysis, study highlights applying fluorescent techniques using chromophores heavy ions, particularly ions. Thus, dyes with modifiable functional groups ensure precise detection offering robust platform monitoring public health safety. We examine capacities, sensing mechanisms, limits, strategies, methodologies utilized. article provides insights into efficacy progress domain sensors detecting

Abstract One of the major obstacles porphyrins is aggregation‐caused quenching (ACQ) photoluminescence due to strong intermolecular π–π interaction planar porphyrin core in solid state. However, ACQ leads nonradiative deactivation photoexcited states which results short‐lived charge‐separated and thus low singlet quantum yields. This phenomenon would limit utilization near‐infrared fluorescent bioimaging, photodynamic therapy, photocatalytic hydrogen evolution, electrochemiluminescence, chiroptical applications. Hence, address property enhance performance above applications, a limited number AIEgen‐decorated have been designed, synthesized, tested for their It has found that introduction AIEgens, such as tetraphenylethylene, diphenylacrylonitrile, (3,6‐bis‐(1‐methyl‐4‐vinylpyridinium)‐carbazole diiodide, iridium motif into core, transformed from aggregation‐induced emission (AIE) state reduced stacking porphyrins. Consequently, containing AIE features are employed potential candidates above‐mentioned In this review, we summarize published date, also discuss benefits converting enhanced within each application. As far know, there no review summarizes structures applications date. Therefore, presume be helpful design more efficient wide range future.

In recent years, metal biomaterials have emerged one after another, and many excellent properties, playing a great role in medicine. However, these coatings cannot meet the medical needs every aspect. Schiff base is an important organic synthetic reagent liquid crystal material chemistry. It mainly refers to class of compounds containing imine or azomethine characteristic groups (-RC=N-). has anti-tumor, anti-virus, antifungal antibacterial activities. Based on properties base, made can improve bioactivity materials, which good development prospect this paper, preparation methods advantages are reviewed. The research modification functional membranes by reaction, as well extensive application special fields such anti-corrosion, antibacterial, flame retardant, etc., carried out. Suggestions for further put forward.

Schiff bases are a crucial component in various functional materials but often exhibit non-emissive behavior which significantly limits their potential applications as luminescent materials. However, traditional approaches to convert them into aggregate emitters require intricate molecular design, tedious synthesis, and significant time resource consumption. Herein, we present cocrystallization-induced emission strategy that can transform (hetero)aryl-substituted green-yellow yellow via even simple grinding of mixture 1,2,4,5-tetracyanobenzene (TCB) mixtures. The combined experimental theoretical analysis revealed the cocrystallization inhibits C=N isomerization promotes face-to-face π-π interaction, restricts access both dark state canonical intersection ultimately induce emission. Furthermore, induced enables observation solid-state diffusion through fluorescence signals, advancing white light diodes, notably, solution-processed organic light-emitting diodes based on cocrystal for first time. This study not only highlights developing new structural motifs AIEgens also could boost advancements related structure like C=C N=N.
